However, with this configuration, it is possible to suppress the end of the neck portion of the surge tank from swinging in the vertical direction of the engine about the line connecting the mounting flange portion of the branch pipe and the upstream end of the branch pipe. Therefore, the occurrence of vibration of the body of the throttle device in this direction cannot be suppressed, and the occurrence of throttle pedal vibration or the like cannot be reliably suppressed. Further, in this configuration, since the tubular member forming the EGR passage is connected to the EGR valve through the mounting flange portion of the branch pipe of the intake manifold, the EGR valve between the EGR valve and the surge tank is provided.
There is also a problem that the length of the passage is long and controllability of the EGR amount is poor.
